[disone]

hey everyone, what i've realised is that in spesh as well as methods there are similar questions that come up almost every year, and i was wondering of anyone had  resources in which the common m=commands and questions that are asked so we can all kill the methods as well as spesh multiple choice. cheers guys

There's this one type of question that comes up frequently, like q10 from 2018 Exam 2, and basically first you define the function f(x):= 1 - x
And then just type in f (x + f (x)) = f (2x) into the CAS.
If it's the answer, it'll come up with true, and if it isn't, the answer will be another equation.
I'll attach a photo of what I mean.
In this question, option c is correct.
